Background
The sponge city is a city which can be like a sponge, has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters and the like, absorbs water, stores water, seeps water and purifies water when raining, and releases and utilizes the stored water when needed. The wetland is an important purification system in sponge cities, can purify scoured water and sewage, and can form a landscape through reasonable design.
According to the runoff mode, the constructed wetland can be divided into three modes: surface flow wetland, subsurface flow wetland and vertical flow wetland. The surface flow wetland is also called a water surface wetland system. In a surface flow wetland system, sewage flows on the surface of the wetland, and the water level is shallow and is mostly between 0.11 and 0.19 m. The system is closest to natural wetland, and the removal of most organic pollutants in sewage is completed by means of a biological membrane growing on stems and rods of the underwater parts of plants. The wetland system has the advantages of low investment and the disadvantages of low treatment capacity, poor sanitary condition and incapability of normally operating in some areas in the north of China due to cold climate in winter; the subsurface flow wetland system is also called a percolation wetland system. In subsurface flow wetland systems, sewage flows inside the wetland bed. Therefore, one side can fully utilize the functions of the biomembrane growing on the surface of the matrix, rich root systems, surface soil, the interception of the matrix and the like so as to improve the treatment effect and the treatment capacity of the biological membrane; on the other hand, because the water flow flows under the ground, the method has the advantages of good heat insulation performance, small influence of climate on the treatment effect, better sanitary condition and the like. The wetland treatment system is a wetland treatment system which is researched and applied more at present. However, the investment of the treatment system is higher than that of a surface flow system, and the nitrogen and phosphorus removal effect is not as good as that of a surface flow wetland system. The water flow in the vertical flow wetland system integrates the characteristics of the surface flow wetland system and the subsurface flow wetland system, the water flow basically presents vertical flow from top to bottom in the matrix bed, and the water flow is collected by a water collecting pipe laid at the bottom after flowing through the bed body and is discharged out of the treatment system. The system has higher requirement on infrastructure and is easy to breed mosquitoes and flies.
